    7x - 1 is correct after combining like terms

    Step-by-step explanation:

    6+8x-7-x

    To simplify algebraic expression we combine like terms

    In the given expression

    -x or - 1x are same

    8x and - 1x are like terms

    6 and - 7 are also like terms

    8x-1x = 7x

    6 - 7 = - 1

    So 7x - 1 is correct after combining like terms
